Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. Its rigid cycloheptane backbone and oxazoline rings provide a well-defined chiral environment, making it effective in metal-catalyzed reactions such as asymmetric hydrogenation and carbon-carbon bond formation. Commonly employed with transition metals like palladium or copper to achieve high enantioselectivity in the synthesis of pharmaceuticals and fine chemicals.
